Title: Synthetic lubricant
Inventor: BLACK JAMES FRANCIS
Filed: 1956-05-29
Abstract: A synthetic lubricating oil composition comprises a blend of a diester with 3 to 5 weight per cent of tricresyl phosphate and 0.5 to 2.5 weight per cent of a metal salt of a sulphonic acid.  The diester is derived from the reaction of a dibasic acid such as sebacic, azelaic or adipic acid with a branched chain alcohol containing for example from 6 to 16 carbon atoms, preferably an oxo alcohol.  The sulphonic acid may be obtained by strong sulphuric acid treatment of petroleum lubricating oils and have molecular weights from 300 to 600, but relatively pure sulphonic acids having 10 to 33 carbon atoms may be used, e.g. the sulphonated products of aromatic hydrocarbons alkylated with olefins or olefin polymers or alkyl sulphonic acids in the 300 to 600 molecular weight range may also be used.  The metal component of the salts may be sodium, calcium, barium, strontium, potassium or magnesium.  Optional ingredients are antioxidants, e.g. phenyl alpha naphthylamine or phenothiazine, viscosity index improvers, pour point depressants, detergent inhibitors, and anti-rust agents.  In examples, the base oil is the diester of adipic acid and a C8 oxo alcohol and the salt either a sodium or calcium petroleum sulphonate.  Phenothiazine is incorporated in one example.

Title: Improvements in or relating to abrasive articles
Inventor: CHANTLER MICHAEL DOUGLAS
IPC: D01F8/04
Filed: 1964-04-25
Abstract: An abrasive article consisting of or containing composite filaments comprises at least two polymer components wherein an exposed component contains particles of an abrasive material dispersed therethrough, which abrasive material has an average particle size not greater than 10 microns.  The term "abrasive material" is defined as including e.g. alumina, diamond and "Carborundum" (Registered Trade Mark), but excluding materials commonly used as delustrants in artificial fibre manufacture, e.g. titanium dioxide.  In an example, a loosely twisted string comprising 225 nylon sheath-core filaments and having protruding silicon carbide particles is used to polish the interior of extrusion dies and similar fine orifices. The components of the composite filament may be in side-to-side or, preferably, in sheath and core relationship with the abrasive material contained in the sheath component.  The abrasive article may be in the form of a yarn or of a continuous filament or staple fibre web. Suitably the exposed component of the composite filaments or fibres has a lower softening point than the other component and the filaments or fibres are bonded together by fusion.  The polymer components may be the same or different and may consist of the same polyamide, e.g. polyhexamethylene adipamide, or one component may be polyhexamethylene adipamide and the other polyepsilon caprolactam or co-polymers thereof; or one component may be a polyamide and another a polyester; or one or more of the components may be a polyhydrocarbon; or any other desired combination of artificial or synthetic polymer components may be used, provided that at least one component is fibre-forming and that the components adhere together to form a unitary structure. In the preferred sheath-core arrangement the core portion of the composite filament should be the load-bearing component so that the strength of the fibre is relatively unaffected by wearing of the sheath portion during use.  The maximum particle size of the abrasive material will vary with the denier of the composite filaments and should always be smaller than the thickness of the sheath portion of the said filaments. Examples are given.ALSO:Silicon carbide, alumina, or diamond abrasive particles of particle size not exceeding 10 microns are incorporated in nylon polymers, copolymers or mixture thereof.  The invention relates to the use of the products as the sheath component of composite filaments (see Division B5).
